Question about Plastruct

Recommended Posts

Which, in your opinion, is better to use for model car building, and why?   Plastic Weld or Bondene?

Plastic Weld is MEK-based (methyl ethyl ketone) and is a more universal solvent, a little "hotter", than Bondene (dichloromethane based).

Bondene sets quicker and is used more for bonding styrene to styrene, ABS to ABS, etc.

Plastic Weld is recommended in situations where you may have styrene, ABS, butyrate and acrylic all in the same assembly...as it's supposed to bond dissimilar plastics a little better.

I've tried them both back to back, and for simply bonding styrene (kit plastic to kit plastic), I've found there to be very little real difference.

I keep them both on the bench, but usually use Plastic Weld for everything.

I should probably do a little serious testing.  :D

Save some geld and get a pint of IPS Weld-On 3 Acrylic Adhesive.

Sixteen bucks for one pint, as opposed to $4-$6 for a 2 oz. bottle of Bondene or Plastic Weld. This is the same as Bondene and I find it an excellent adhesive.

Is Plastruct made of styrene now? I used some long ago and it wasn't. MEK glues wouldn't bond it, had to be something MC based. This is why I switched to Evergreen long ago.

It depends on the specific product, which is where reading the label can be of value.

Some is butyrate, hard to bond, but most of it's styrene.

ONLY the WHITE Plastruct is Styreene . The Grey , the White THICK WALL and the Dark Grey is Poly Butyl  !
